How can I generate code using Simulink PLC Coder for fminsearch function?

Hi, I'm trying to generate code for a MATLAB Function Block where I use the method fminsearch in Simulink, but I get some errors.
I decided to create a model with just the MATLAB Function Block and a code using fminsearch (as simple as possible) like this:
function y = myfminsearch(u)
%#codegen
y = fminsearch(@myfun,u);
function f = myfun(x)
f = (x+5)^2+5;
Even if the method is supposed to work for code generation I get this error:
Call to unsupported function 'frexp' detected.

Can you see what the problem is? I don't really understand the error... Do you think I can't use fminsearch for code generation?
Thank you guys!

I have the same problem. the @ character is not supported I thing you have to write fminsearch('myfun',x,options)
